NX 10 NASTRAN Temperature loads inactive

[chamansrv]

I have been trying to do a thermal analysis using NASTRAN, but the thermal loads are inactive even if I have applied them. what should I do? The simulation navigator says so.

Hi Chamansrv,

Did you select the correct solution? I think for thermal analysis, you need to select Sol 153 or Sol159...

I am using SOL 153 as my solver. I have created temperature sets, and the temperature are active =500C, but the load subcase is empty and the temperature are added to the "Temperature" case in solution box. When the model is processed, the temperature profile shows that geometry has temperature of the constraint -"Thermal constraint= 25". And shows no signs of the temperature loads. My sample is metallic and I'm using NX 10.02 version.

Hi,

Possible to share your work files?

Dear Tuw,

Work files? do you mean .dat or .f06 files?

Best Regards
